And I see 1,389 results that pass. And hundreds of other modules that depend on it so it installs just fine for a ton of people. Besides, a DNS error is hardly a problem when the focus of the code isn't name resolution. They could have installed the module without bothering with the test suite so I'm not sure what the goal is.

I'd suggest crabbit switch to HTTP::Tiny with SSL support properly installed. Less to bother with because HTTP::Tiny has been a core module for 13 years now.
